How to Make Steak Fajitas in the Air Fryer
Start by slicing the bell peppers and onions into thin, even strips. Slice the skirt steak into ¼-inch strips, too.
- Step 1: Season and Coat the Vegetables. Place your sliced bell peppers and onions in a medium bowl, then add 1 tablespoon olive oil and 1 teaspoon salt. Use your hands to toss everything together, making sure each piece is well-coated with oil. This helps them caramelize beautifully in the air fryer.
- Step 2: Cook the Vegetables. Preheat your air fryer to 350°F for 3 minutes. Add the seasoned vegetables to the basket in an even layer and cook for 12 minutes. Shake the basket halfway through at the 6-minute mark to ensure even cooking and caramelization.
- Step 3: Prepare the steak. While the vegetables are cooking, toss your sliced steak with fajita seasoning, ½ teaspoon salt, 1 teaspoon olive oil, and the chopped pepper in adobo sauce until evenly coated.
- Step 4: Cook the Steak. When the vegetables are done, add the seasoned steak on top and continue cooking for 10 more minutes at 350°F, shaking the basket halfway through.
- Step 5: Warm Tortillas and Serve. During the last few minutes of cooking, warm your tortillas either in the microwave (wrapped in a damp paper towel for 30 seconds), in a dry skillet, or directly over a gas flame for a slight char. Transfer your sizzling fajita mixture to a serving plate and immediately serve with warm tortillas, fresh lime wedges, cilantro, sour cream, and any additional toppings you love.
Hint: Slice Evenly
Make sure your beef and vegetables are all sliced about the same size. This way they will all cook in the same amount of time.
Expert Tips
- When Feeding a Crowd: Work in batches so the air fryer doesn’t get overcrowded. You should easily be able to shake the ingredients during cooking time so everything cooks evenly.
- Slice Against the Grain: When cutting your skirt steak or flank steak, slice against the grain (perpendicular to the muscle fibers). This will help make the bites tender instead of chewy.
- Storing: Store the steak and veggie mixture separate from the toppings and tortillas. Leftovers will keep in an airtight container for up to 3 days. Reheat the dish in the microwave on medium heat for 30-60 second intervals or in a skillet on the stove until it is heated through.
- Boost the Flavor: You can marinate the top sirloin strips in the fajita seasoning, salt, and olive oil for at least 30 minutes before cooking. This allows the flavors to penetrate the meat, making it more flavorful.
Serving Suggestions
These sizzling steak fajitas go well with a variety of sides and they make a great weeknight meal or weekend dinner. Here are some ideas for how to serve them.
- Have air fryer beef fajitas with dips as an appetizer. Serve tortilla chips with 7 layer taco dip and crack corn dip.
- Pair them with Mexican rice and classic refried beans for an authentic Mexican meal at home.
- Garnish with sliced radishes, pickled red onions and jalapenos, and crumbled cotija cheese.
- Set up a build your own fajita bar and let everyone customize their toppings. Serve with fresh homemade guacamole, authentic pico de gallo, and restaurant style salsa.
Recipe FAQs
You can prep all the components 1-2 days ahead for easy assembly. Slice the vegetables and meat, mix the seasoning, and store everything separately in the refrigerator. For an even quicker meal, you can fully cook the fajita mixture, refrigerate it, and simply reheat when ready to serve. The flavors develop well overnight!
You may have overcooked the meat or used a cut that's not the best for the recipe. Also, make sure you slice the steak across the grain.
If your air fryer has a tray style, use tongs to flip the ingredients over halfway through the cooking time.
